response, multi-material ultrasonic, proximity ries of proximity sensors as a re- placement for inductive proximity sensors and fixed-field photoelec- tric sensors. Its long range, small size, fast response, performance, reliability, and low cost, offers a simple, easy to use,once-and-for- all solution to many of the prox- imity sensing problems encoun- tered daily in almost every indus- provides reliable detection of ob- sensor face, performance un- matched by other proximity sen- sors of the same size or larger. At this distance, the sensor is safely out of harms way, that is an especially important cost sav- ings benefit. Easy to install, the threaded barrel or the flat-profile housing both available in ULTEM® plastic. As with all SUPERPROX® sensors, cable and connector pable of automatically detecting all materials regardless of color, shape, and composition (trans- parent or opaque, liquid or solid) including clear glass, mirrors, wood, powder, ink, ferrous and nonferrous metal, plastics, and objects that change colors. While some sensors require adjustment tects most materials automati- cally.

It is an ideal solution for sensing part and pin presence stamping dies. Other applica- tions include die open and close detection in stamping, plastic in- jection molding, die casting ap- plications, and many other ap- plications where traditional prox- imity sensing methods cannot re- liably detect the large variety of materials running through the pro- cess or they are limited by sens- tained, pulse-echo, proximity sensing device that both trans- mits and receives sonic energy within an operating distance of The sensor combines the latest technology for the best possible performance in almost any sens- This 500 kHz proximity sensor equipped with both sinking (NPN) • Extended sensing • Field programmable proximity sensing sensor has two status LEDs: a green LED indicates "power on" when no object is present, and an amber LED indicates object presence, regardless of output is illuminated at any given time. During operation, the sensor transmits to and receives sonic pulses from objects in front of it without interruption. A discriminat- sible for the sensor to accept only those pulse echoes received from objects within the fixed sensing window limits and ignore all other objects. An object is detected when it is within the fixed sens-

During setup and operation, the SM300 series sensor continually and accurately measures the elapsed time of every pulse echo reception after each pulse transmission. The transmitted pulse starts a time clock to register the elapsed time for the received pulse ech- oes. Given the elapsed time, the sensor software calculates the distance traveled to the object or surface and back to the sensor, using the formula, D = TVs/2, where D = distance from the sensor to the object; T = elapsed time between the pulse transmission and its echo re- ception; Vs = the velocity of sound, ap- proximately...
